"That was it."
"That is a state where it gives out white heat."
"I thought everything at the sun must be on fire," said Daisy looking meditatively at the doctor.
"You see you were mistaken. It has only a covering of clouds of fire—so to speak."
"But it must be very hot there."
"It is pretty hot here," said the doctor shrugging his shoulders,—"ninety five millions of miles away; so I do not see that we can avoid your conclusion."
"How much is ninety five millions?"
"I am sure I don't know," said Dr. Sandford gravely. "After I have gone as far as a million or so, I get tired."
"But I do not know much about arithmetic," said Daisy humbly. "Mamma has not wanted me to study. I don't know how much one million is."
"Arithmetic does not help one on a journey, Miss Daisy," said the doctor pleasantly. "Counting the miles did not comfort me to-day. But I can tell you this. If you and I were to set off on a railway train, straight for the sun, and go at the rate of thirty-two miles an hour,—you know that is pretty fast travelling?"
